# operation on tuples in pythons:

# to make change in tuple , first we need to change the tuple into list then, make  change in that list and finally change the list into the tuples: for example-
countries = ("Spain", "Italy", "India", "England", "Germany")  #tuple
temp = list(countries) #tuple is converted into list
temp.append("Russia")       #add item
temp.pop(3)                 #remove item
temp[2] = "Finland"         #change item
countries = tuple(temp)
print(countries)

countries = ("Pakistan", "Afghanistan", "Bangladesh", "ShriLanka")
countries2 = ("Vietnam", "India", "China")
southEastAsia = countries + countries2

tuple1 = (0, 1, 2, 3, 2, 3, 1, 3, 2)

res2 = tuple1.index(3)
res3 = tuple1.index(3, 4, 8)  # tuple.index(element, start, end),   #Note: This method raises a ValueError if the element is not found in the tuple.
